Latter TO8 models did include Video mode similar to Amstrad CPC's ones, inb addition to a 16 colours character attributed mode (like on speccyMSX1 or Spectrum...more like the MSX1 though...) and a 4096 colour palette. also Also those latter models included more RAM than Amstrad's 8 bit computers.
But those computers were lacking a decent sound chip : Even the AY seems like a sifd in comparison.
